DJI backpack for ph3a problem

Hi guys,
my 2 months old original DJI backpacks strap started to cause a problem. It's seam is "peeling off". I know it will only get worse with time and the strap will eventually fall off.
Does the backpack have any warranty? What can i do about it? I have taken care of it and i'm that really makes me disappointed. Can someone relate?
It's the early stage, but i know where this is going...
